Working fine with output as well but How can i assign 365 and 366 to a single variable X

Question about the task

Under discussion

As the condition says Number of days in the year: x , where x is 366 for a leap year, and x is 365 for an ordinary year. I think the CORRECT output line of code like this -->System.out.println(Number of days in the year: x). it should NOT be like as I've done on line 18 & 21. Intelli J Idea ISSUE : This is with the reference variable stryr (in ide it is underlined green) on line 14. when i move cursor over this in IDE it shows Typo: in word stryr Why it is so? And more thing what does this yellow bulb indicates in IDE if everything is fine.

Use the keyboard to enter a year, and then determine the number of days in the year. Display the result as follows:
Number of days in the year: x
, where
x is 366 for a leap year, and
x is 365 for an ordinary year.

Hint:
A leap year is 366 days, but an ordinary year is 365 days.
1) if the year is evenly divisible by 400, then it is a leap year;
2) for other years, if the year is evenly divisible by 100, then it is a regular year;
3) for other years, if the year is evenly divisible by 4, then it is a leap year;
4) all remaining years are not leap years.
Thus, the years 1700, 1800, and 1900 are not leap years, since they are multiples of 100 but not 400.
The years 1600 and 2000 are leap years, since they are multiples of 100 and multiples of 400.
The years 2100, 2200 and 2300 are not leap years.

Requirements:

The program should read a number from the keyboard.
The program should display text on the screen according to the task conditions.
If the entered year is a leap year, you should display: "Number of days in the year: 366".
If the entered year is not a leap year, you should display: "Number of days in the year: 365".

package com.codegym.task.task04.task0414; /* Number of days in the year */ import java.io.*; public class Solution { public static void main(String[] args) throws Exception { //write your code here BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String stryr= reader.readLine(); int yr = Integer.parseInt(stryr); if (yr%400==0 && yr%100==0 && yr%4==0 ) System.out.println("Number of days in the year: 366 "); else System.out.println("Number of days in the year: 365"); } }

Hey, it could be a grammar problem. Check that what you write in is exactly the same as what the condition requires. Even spaces that shouldn't be there could affect whether or not the condition is met.

To get System.out.println("Number of days in the year: " + x); you can declare the x integer inside the if else statement. For example:

if (yr % 400 == 0 && yr % 100 == 0) {
int x = 366;
System.out.println("Number of days in the year: " + x);
}

Your condition yr%400==0 && yr%100==0 && yr%4==0 Will not work for years like 2020, or 2016. these are leap years however they are not divisible by 100 or 400. I would suggest making two conditions: 1: (y%400 == 0 && y%100 ==0) 2: (y% 4 == 0) Also I assumed they wanted us to create a variable x and make it equal to 366 or 365 depending on the condition, and format the System.out.println statement accordingly.

To Keep it simple Take a look at this : For 400 and 100 = 366; For 100 = 365; For 4 = 366; Else if nothing matches then 365... OR if (years % 400 == 0 && years % 100 == 0){ System.out.println("Number of days in the year: 366"); } else if (years % 100 == 0 ){ System.out.println("Number of days in the year: 365"); } else if(years % 4 == 0){ System.out.println("Number of days in the year: 366"); } else { System.out.println("Number of days in the year: 365"); }
